# Fedora-clean shared-lib build (upstream is static-only / superbuild-oriented).

# Minimal CLAPACK prototype shim (Fedora dropped clapack; symbols come from

%description
rr-libstruct (libStructural) computes structural properties of biochemical
reaction networks from their SBML stoichiometric matrices — conservation laws,
the link/gamma matrices, fully/partially-reduced stoichiometry, and related
linear-algebra analyses. It is a core dependency of libRoadRunner.

%changelog
* Wed Jun 17 2026 Morgan Hough <morgan.hough@gmail.com> - 2.9.2-0.2.git7ff1f47
- Export a CMake config (rr-libstruct::rr-libstruct-static target) so
  libRoadRunner's find_package(rr-libstruct CONFIG) resolves.

* Wed Jun 17 2026 Morgan Hough <morgan.hough@gmail.com> - 2.9.2-0.1.git7ff1f47
- Initial package: rr-libstruct (sys-bio) as a Fedora-clean shared library.
- Replace upstream static-only/superbuild CMake with a shared build linking
  system libSBML + Fortran LAPACK/BLAS; supply a minimal clapack.h prototype
  shim (f2c.h from the system f2c package). Foundation dep for libRoadRunner.
